Application filed September 30, 1919:.

T 0 all ttf/0m it may concern Be it known that I, GEORGE E. NnUBnn'rI-I, a citizen of the United States, and a resident of Newark, county of llssex, and State of New Jersey, have invented certain new and usei'ul improvements in Transom-Operating` Devices, of which the following is a specification.

l'his invention relates to a transom operating device and is adapted to provide a device that is manually operated to close or open a transom, the operating means being of such construction that it acts to hold the transom whenever the operating means stops so that no additional locking or holding operation is necessary.

ln order to provide a structure as above outlined, l employ a lazy tongs which is connected at one end to the transom and at the opposite end to a means for spreading and also for drawing together the end of the lazy tongs so that the tongs are extended or collapsed, as desired. This means igor spreading or drawing together the lazy tongs end l call the operating means, and it is made so that it holds whenever it is stopped, so that it locks the lazy tongs, and consequently the transom, against moi ement.

The preferred orm of operating means is a screw with part oit its thread righthanded and part left-handed, one part being in screw-threaded engagement with the end of one lever of the lazy tongs, and the other part being in such engagement with the end of another` lever of the lazy tongs, so that the ends are moved together or apart, accordingr to the direction of rotation of the screw.

rlhe device is cheaply constructed and occupies but little space, being usually concealed by being placed in the frame of a door and extending vertically on the inside of the frame with a connection through the frame to the pivot orn the transom.

The invention is. illustrated in the accompanying drawing, in which is shown one embodiment of my invention.

ln said drawing, Figure 1 is a front view of part of a door frame equipped with my improved transom operating device, the frame being broken away at the pivot oli the transom. Fig. 2 is a side view of the invention as illustrated in Fig. 1.

l illustrate a portion of a door frame with the side frame i0, a cross piece or head piece l1 and a transom l2. The transom, as

shown, is pivoted at the bottom, but it will be evident that it can be pivoted at any suitable point at the sides.

lThe pivoted connection shown consists 03'. a plate 13 secured at the lower corner of the transom, the plate having a stem 14 with a squared end 15. The stem passes through a bushing 16 with a flange 17 at its outer end. the bushing acting as a bearing for the stem, being placed in the side plate or board 18 ot' the door frame. n arm 19 has a square hole in one end, which hole receives the square end 15 oli the stem 141-, and is held in place by a washer Q0 and a screw Q1, although other fastening means may be used.

lit a suitable point in the side frame 10, is placed the operating means for manipulating the transom, in the form shown this being in the form of a rod Q2 which passes through an escutcheon plate 23 which has a sleeve @il extending through the front plate or board 25 of the door frame. The rod 22 at its rear end which is screw-threaded, as will be hereinafter described, is thereby provided with a shoulder 22 which bears normally against tne washer 22h which takes up the thrust of the screw and prevents longitudinal movement of the rod. The rod is provided with any suitable form of handle 2G. rIhe rod is screw-threaded, the screw being right-handed at one section thereof, as at 27, and lett-handed at another, as at :28.

Beneath the screw is a guide 29 having grooves 3() in its side edges, the guide being secured as by the screw 31 to a suitable support or blccl Arranged to slide on the slide 29 are bloclzs 33 and 3i which have screw-threaded perforations to receive their relative sections 28 and 27 of the screwthreaded rod 22. The blocks have tongues 35 to enter the grooves 30.

A. lazy tongs is mounted on the blocks, the tongs consisting of lower crossed levers 36 and 37 secured at their bottom edges to the blocks 33 and 34, and pivoted at their centers, as at 38. Pivoted to the upper end of the lever 36 is a short lever 39, and to the upper end of the lever 37 is an upper lever l0 which is pivoted at l1 to the short lever 39, and extends beyond the pivot Ll1 and has at its upper end 4:2 a pivoted connection with a bar 43, the bar @i3 being connected at its upper end to the arm 19, as at 44e.

1t will be evident that as the vertically disposed lazy tongs is extended horizontally ,28 draw the blocks toward each other when the rod is rotated in one direction, and push them farther apart when the rod is rotated in the opposite direction. When the rotation of the screw is stopped, the screw acts to hold the blocks in the positions they occupy when the screw stops. The operation oi' the handle insures the swinging of the transom, and the cessation oil such operation locks the operating mechanism, and consequently the transom, against any movement. This feature obviates the necessity of using two hands to operate or lock the transom, and also prevents the swinging of the transom, as in an attempt at burglary, or in the case of a strong wind it prevents rattling.

Having thus described my invention, I claim:

1. A transom operating device comprising a lazy tongs connected at the top to a transom, blocks secured to the bottom end of the lazy tongs, a slide on which the blocks are movable, a right and left handed screw passing through the blocks, and a handle for operating the screw.

2. A transom operating device comprising a lazy tongs connected at the top to a transom, a slide with grooved sides, blocks sliding on the slide and having tongues eX- tending into the grooves, the blocks being connected to the bottom of the lazy tongs, and means for varying the distance between the blocks, said means also acting to lock the blocks in different relative positions.

3. A transom operating device comprising a lazy tongs connected at the top to a transom, a slide with grooved sides, blocks sliding on the slide and having tongues extending into the grooves, the blocks being connected to the bottom of the lazy tongs, a right and left handed screw passing through the blocks and in engagement therewith, and a handle for operating the screw.

4. A transom operating device comprising an arm adapted to swing, a vertically disposed lazy tongs, a connection between the top of the lazy tongs and the arm, sliding blocks at the bottom oi' the lazy tongs, a slide for the blocks, a right and left handed screw passing through the blocks, and a handle on the screw :tor rotating it.

5. A transom operating device comprising a lazy tongs consisting of crossed levers pivoted to each other at their ends and where they cross at the center, a rod extending from the end of one of the levers at the top of the lazy tongs to a transom moving means, and means tor varying the distance between the ends of the levers at the bottom of the lazy tongs.

6. A transom operating device comprising a lazy tongs consisting of crossed levers pivoted to each other at their lends and Where they cross at the center, a rod extending from the end of one of the levers at the top of the lazy tongs to a transom moving means, blocks at the ends of the levers at the bottom of the lazy tongs, a slide on which the blocks move, a right and left handed screw passing through the blocks, and means for rotating the screw.

In testimony that 1 claim the foregoing, I have hereunto set my hand, this 28th day of September, 1914.
